Analog pin as output pin ?

rishi2628 over 10 years ago

Is there any way i can use the analog input pins of an atmega328p microcontroller to give output? All my other digital I/O pins have been used up.

Analog (A0, A1, A2, ...) pins can be used as digital pins, so you could use them with "digitalWrite()". pinMode(A0, OUTPUT); digitalWrite(A0, HIGH); digitalWrite(A0, LOW);

Yup, just use them in the same way as the digital ones and it will work just fine

I think you'll also find this works pinMode(14, OUTPUT); digitalWrite(14, HIGH); digitalWrite(14, LOW); Mark
